5.25 miles very easy.
I've been looking over my blog for the last couple years and I've discovered some interesting things. I ran my marathon PR (2:43) at Utah Valley in 2010. Prior to that my PR was almost 10 minutes slower and I had only broken 3 hours four times. In retrospect I could have run that UVM several minutes faster if I had been a little more confident in my fitness. I ran my last mile in 6 minutes and felt great at the end.
That year I did a grand total of two 70 mile weeks in the four months leading up to the race. Most of my weeks were in the 50-65 range. So far this year I have run eleven seventy plus mile weeks since December leading up to Boston.
So I shouldn't have any problem breaking 2:40 at Boston right? I am two years older though.
